View Full Version : sigma 600mm F8 reflex

15th July 2009, 03:18 PM
Looking for advice again please!:confused:

Browsing the Ffordes list of used stock today and they have one of these lenses listed for 99 (plus I would need to buy an om to 4/3 adapter).

Does anyone have any knowledge of this (or a similar) lens and whether it would be worth buying for wildlife shots or should I just keep saving for perhaps a 135-400 or a "Bigma"?

I am still learning and experimenting with my e510 and 70-300 lens but am a very very long way from the standard I have seen in the pictures displayed by other forum members!

Thanks in advance, Kevin

I guess the biggest problem is manual focussing an f8 lens

Although the likes of the bigma needs stopping down a bit a/ its auto focus and b/ its a bit brighter open

I have one of these and it is really quite good. I've tried several from 400mm conventional, 500mm mirror and the Sigma 600 provides acceptable results.

The obvious issue is stability. At 1200mm eqivalent anything that is not an absolutly solid base to work off will show up in the image. I've tried tripods & clamps mounts but the best thing is a simple bean bag and use the remote control or self timer (also turn on anti-shake). With a good solid base I found that I got better results with IS off.

Make sure that the one you get has no fungus and has the 4 filters with it.

I enjoy using these Super Teles and the mirror can also be used close in as well with some super results on the out of focus highlights.

Do show some results if you get it.


PS 99 is a good price.

Hi, personally I've no experience of the lens at all, however a guy with the pen-name of First Light used to post some very well informed reviews of lenses on another site.

I actually find the lens very good for the reach it offers and humble price.
I can handhold the lens but a tripod will allow you to use live view and a shutter release if required.


Some other galleries (not mine)







So it depends what you want to use it for?

Thanks to all for your prompt replies and opinions.

The review that Bill referred me to seems to contradict the experience of forum users and on balance I'm currently tempted to have a punt for the relatively small sum of money involved!

Thanks again, Kevin

Hi, despite the link I posted, I'd be tempted to try it too, if I didn't already have an exess of glass things.
If you don't get on with it, I'm sure it would fetch good money on ebay or similar.
Let us know how you get on with it, hopefully for you lots of folks will be kicking themselves for not buying it.:)

At 99 you're hardly breaking the bank even if it may delay getting a Sigma 135-400, which is a very good lens.

The September editon of Outdoor Photography carries a London Camera Exchange advert for Samyang 800mm f8 at 300 and 500mm f6.3 at 200 mirror lenses. T2 mounts are extra from 15. Does anyone have any experience of these please?

The same issue also carries a fulsome review of the E620 giving it 95% (the same as the D3X some months back). The only dislike was noise at high ISO.

The other issue with mirror lenses (other than the fixed, relatively small aperture, that is) is the out-of-focus highlights, which always have a doughnut shape. Some find them unacceptable - personally, I quite like the effect.

In their favour, however, is the light weight and small size. I therefore persevered on and off with a Sirius 500mm f8.8 for years - and live view on the E-series finally made it a viable proposition. Sufficent, at least, to demonstrate the fairly poor quality of the lens, but to confirm that the principle of using a catadioptric lens was worth pursuing. Focusing was previously always a nightmare, even with the (much) larger OM 35mm viewfinder.

I now have a Tamron SP 500mm - unfortunately I rarely have an opportunity to use it as the f8 aperture and manual focus still means it's of limited use in all but very good light. Nevertheless, I did splash out the 25 or so extra for a Tamron SP 2x teleconverter despite the resultant f16! Ultimately, however, my 135-400 actually gets a lot more use. I agree with Graham about bean bags rather than tripods (plus a carabiner and some cord to stop the bag falling out of the hide window!).

Another issue worth mentioning with any extreme telephoto is haze - always a problem at long range here in the south east.

Not sure about the Samyangs - I would go for a recognised legacy catadioptric like Sigma, Tamron (or of course, Olympus) as you know you'll be able to sell it for something like what you paid for it should you decide it doesn't suit your style of photography.

Thank you. Very helpful.
